中文摘要：
本研究主要是針對大鵬灣及高屏海域的仔稚魚進行週年而有系統的調查，以探討這兩個海域仔稚魚之種類組成、數量分佈及其與溫度、鹽度、葉綠素a濃度和橈足類豐度之相關性。
綜合1999年6月至2001年12月期間於大鵬灣所採集到的樣品分析結果，共鑑定出仔稚魚種類16科29屬31種，平均豐度為22.9 ±40.7 ind./100m3，仔稚魚平均豐度在年度間之季節變化趨向並不太一致，但一般以春或夏季時較高。大鵬灣內的仔稚魚主要優勢種為Omobranchus sp.、Tridentiger obscurus、Pterogobius zonoleucus、Blenniidae gen. sp.、Gobiidae gen. sp.、Entomacrodus lighti及Engraulis japonicus，這7個主要優勢種佔了全部仔稚魚豐度的94%，其中第一及第二優勢種就佔了高達80%。
1999年6月至2001年6月期間於高屏海域7個測站的樣品分析結果，共發現仔稚魚種類69科130屬184種，年平均豐度為390.6±593.5 ind./100m3。整體來看，仔稚魚豐度呈現明顯的季節性變化，於冬季（12月）時最低，然後逐漸增加，夏季（6月）時達到最高峰。仔稚魚主要優勢種為Sillago japonica、Engraulis japonicus、Tridentiger obscurus、Gobiidae gen. spp.、Pagrus major、Scomberoides lysan、Leiognathus nuchalis、Ceratoscopelus warmingi、Scatophagus argus及Diogenichthys laternatus等，這前10個主要優勢種佔了全部仔稚魚豐度的67%。
比較大鵬灣及高屏海域仔稚魚種類組成後發現，高屏海域之仔稚魚不論在平均豐度、種類數或種歧異度上，均較大鵬灣內高出許多。大鵬灣內仔稚魚種類是以砂泥底質性（

Abstract：
The principal objectives of this research are to investigate the species composition and distribution of larval fish in relation to water temperature、salinity、chlorophyll a and the abundance of copepods in Tapeng Bay and Kaoping coastal waters.
Thirty-one species of the larval fish belonging to 29 genera and 16 families were identified in Tapeng Bay, with the mean numerical abundance of 22.9 ±40.7 ind./100m3 during the sampling period between June 1999 and December 2001. The trend of seasonal change in numerical abundance of the larval fish was not coincident interannually. The 7 most dominant species were Omobranchus sp., Tridentiger obscurus, Pterogobius Zonoleucus, Blenniidae gen. sp., Gobiidae gen. sp., Entomacrodus lighti and Engraulis japonicus, occupied 94% of the total larval fish abundance；among these, the first two dominant species, Omobranchus sp. and T. obscurus contributed to 80% of the total count.
One hundrad and eighty-four species of the larval fish belonging to 130 genera and 69 families were identified in Kaoping coastal waters, with the mean numerical abundance of 390.6±593.5 ind./100m3 during the sampling period between June 1999 and June 2001. Generally, the numerical abundance of the larval fish showed significantly seasonal changes, with lowest in winter and up to highest value in summer. The 10 most dominant species were Sillago japonica, Engraulis japonicus, Tridentiger obscurus, Gobiidae gen. spp., Pagrus major, Scomberoides lysan, Leiognathus nuchalis, Ceratoscopelus warmingi, Scatophagus argus and Diogenichthys laternatus, occupied 67% of the total larval fish abundance.
The mean abundance, species number and species diversity index of the larval fish were obvious higher in Kaoping coastal waters than in Tapeng Bay. The dominant species of larval fish in Tapeng Bay were mostly sandy benthic species (Blenniidae and Gobiidae) and coastal epipelagic species (Engraulidae). The larval fish assemblage in Kaoping coastal waters was diverse, and dominated by benthic species (Sillaginidae), sandy bottom species (Blenniidae and Gobiidae), coastal epipelagic species (Engraulidae), mesopelagic species (Myctophidae) and coastal-migrant species (Scatophagidae).
